If you followed our Disabling Unnecessary Services tutorial
on a Windows XP Professional system with Service Pack 1 installed,
you can reduce the running services to a minimum level
of 31 essential services need to be running in "Automatic" or "Manual" mode.
All other 56 services can be disabled.

With less services running, your system will need less than 250MB of memory to start up.
This will greatly boost your system performance.

The suggested minimum set of running services can still allow you to visit Internet and use all local network services.
